Sex steroid hormones in meat, eggs, and dairy may help explain the link between saturated fat intake and declining sperm counts.
A study of 13 over-the-counter children’s fish oil supplements found that all were contaminated with PCB pollutants.
How do the blood-pressure lowering effects of hibiscus tea compare to the DASH diet, a plant-based diet, and a long-distance endurance exercise?
Is the reversal of cellular aging Dr. Dean Ornish demonstrated with lifestyle changes due to the plant-based diet, the exercise or just to the associated weight loss?
Feed contaminated with toxic pollutants thought to originate from sewer sludge fed to chickens and fish results in human dioxin exposure through poultry, eggs, and catfish.
The emergence of pathogens resistant to even our antibiotics of last resort has raised the specter of a “post-antibiotic age” in which drugs to fight infections may be useless. This has focused attention on the mass use of antibiotics in farm animal feed to promote growth and prevent infection in high density production.
By testing chicken feathers for chemical residues, researchers aim to find out what the poultry industry is feeding their birds. The presence of banned drugs and a broad range of pharmaceuticals raises concern, recalling the time in which DES was fed to chickens for years after it was shown to cause human vagina cancer.
Neurotoxins in chicken, such as the beta-carboline alkaloid harman, may explain the link between meat consumption and hand tremor, the most common movement disorder.
How do sweet cherries compare to the drug allopurinol and a low-purine diet for the treatment of the painful inflammatory arthritis gout?
Nutritional quality indices show plant-based diets are the healthiest, but do vegetarians and vegans reach the recommended daily intake of protein?
The rising incidence of tick-bite induced meat allergies may account for cases of previously unexplained (“idiopathic”) persistent hives among children.
Industrial pollutants that build up in our own body fat may help explain the link between obesity and diabetes.
The relationship between fish consumption and diabetes risk may be due to toxic pollutants that build up in the aquatic food chain.
The association between cancer and the consumption of deep-fried foods may be due to carcinogens formed at high temperatures in animal foods (heterocyclic amines and polycyclic hydrocarbons) and plant foods (acrylamide).
What if billions in tax dollars were invested in healthier options, rather than given to corporations to subsidize the very foods that are making us sick?
The levels of arsenic, banned pesticides, and dioxins exceeded cancer benchmarks in each of the 364 children tested. Which foods were the primary sources of toxic pollutants for preschoolers and their parents?
The lifespan extension associated with dietary restriction may be due less to a reduction in calories, and more to a reduction in animal protein (particularly the amino acid leucine, which may accelerate aging via the enzyme TOR).
Phytic acid (phytate), concentrated in food such as beans, whole grains, and nuts, may help explain lower cancer rates among plant-based populations.
Foods of animal origin (especially fish) appear to be the most important source of human exposure to industrial pollutants such as alkylphenol xenoestrogens.
The dramatic rise of allergic diseases such as eczema and seasonal allergies may be related to dietary exposure to endocrine-disruptor xenoestrogens, such as alkylphenol industrial pollutants.
Used in about eight million pounds of meat every year in the United States, the “meat glue” enzyme, transglutaminase, has potential food safety and allergy implications.
Different brands of liquid smoke flavorings have been tested for DNA-damaging potential, p53 activation, and levels of known carcinogens. Smoked foods such as ham, turkey, barbequed chicken, herring, and salmon were also tested.
Advice to eat oily fish, or take fish oil, to lower risk of heart disease, stroke, or mortality is no longer supported by the balance of available evidence.
How many months does it take to clear 99% of the mercury and other industrial toxins from one’s body, and what role might our fat stores play in holding on to fat-soluble pollutants?
The carotid arteries of those eating plant-based diets appear healthier than even those just as slim (long-distance endurance athletes who’ve run an average of 50,000 miles).
To stay out of oxidative debt, we need to take in more antioxidants than we use up.
Even nine servings of fruits and vegetables a day may not reach the minimum recommended intake of antioxidants if one doesn’t make the right choices.
Risk/benefit analysis of 33 fish species contrasts the brain-boosting effects of DHA with the brain-damaging effects of mercury, to determine the net effect on intelligence (IQ).
Exposure to mercury during pregnancy appears to influence fetal brain development, as detected by decreased size of a newborn’s brain.
Phytonutrients in certain plant foods may block the toxic effects of industrial pollutants, like dioxins, through the Ah receptor system.
Americans eating meat-free diets average higher intakes of nearly every nutrient, while maintaining a lower body weight—perhaps due, in part, to their higher resting metabolic rates.
Too much choline—a compound concentrated in eggs and other animal products—can make bodily secretions smell like rotting fish, and may increase the risk of heart disease, due to conversion in the gut to trimethylamine.
The beef industry designed a study to show that a diet containing beef was able to lower cholesterol—if one cuts out enough poultry, pork, fish, and cheese to halve one’s total saturated fat intake.
Plant-based diets tend to be alkaline-forming. This may help protect muscle mass, and reduce the risk of gout and kidney stones. The pH of one’s urine can be estimated with natural pigments, using kitchen chemistry.
The decades-old dogma that the acid-forming quality of animal protein leads to bone loss has been called into question.
Methionine restriction—best achieved through a plant-based diet—may prove to have a major impact on patients with cancer because, unlike normal tissues, many human tumors require the amino acid methionine to grow.
A higher rate of cancer deaths among those that handle and process meat is attributed to infection with viruses, and chronic exposure to animal proteins.
Those eating a more plant-based diet may naturally have an enhanced antioxidant defense system to counter the DNA damage caused by free radicals produced by high-intensity exercise.
